The number of batches she can make is = 5 batches
<h3>Calculation of total number of batches</h3>
The amount of dough used to make each batch = 12oz
The total amount of dough she has= 60oz
Therefore, the number of batches she can make from the total dough available = b
Using the equation:
(dough for one batch) × (number of batches) = (total amount of dough)
which is = 12× b = 60
b= 60/12
b= 5 batches
